The museum and educational event «The Feast of the First Street» is dedicated to the first street of the city of Nefteyugansk - Yuri Gagarin Street. The event was first held in 2011. Subsequently, it became traditional and is held annually on the last Saturday of August. In 1961, the Ust-Balykskoye oil field, unique in its reserves, was discovered. The first landing party of prospectors and builders landed on the high bank of the Yuganskaya Ob. Residents of the Nefteyugansk work settlement named their first street in honor of Yuri Gagarin, the same discoverer as them. The program of the event includes interactive and thematic platforms, exhibitions, creative workshops and games for children, theatrical productions and performances, concert programs
